SPECIFICATION forming pari. of Letters Patent No. 391,236, dated October16, 1888.

Application lod October i7, 1387.

T @ZZ whom if; may concern:

Be it known that I, XVILLARD II. FULLER, otPassaic, county of Passaic,State ofNew .Iersey, have invented a cert-ain new and useful Improvementiu Photographic Cameras, of

which the following is a specification.

My improvement particularly relates to the kind ot'photographic cameraswhich are known as detective cameras.

The object ofmy improvement is to simplil'y and cheapen such cameras.

I will describe a camera embodying my improvement, and then point outthe novel features in the claims.

In the accompanying drawings, Figure l is a front view ot' a cameraembodying my improvement, the face of the case being removed. Fig. 2 isa central vertical longitudinal section of the saine. Fig. 3 is aninverted plan or bottom view. Fig. @t is a transverse vertical sectionof the lower portion of the camera. Fig` is a horizontal section ol1certain portions of the camera. Fig. (i is a side view of the camera.

Similar letters of reference designate corresponding parts in all thelgures.

A designates the case of the camera. It is made in the form ot arectangular box and preferably of thin wood, so as to be as compact andlight as possible. It is composed ol" four compartments or chambers, ca2 c a". The main chamber or compartment c' has a ibcusiug-platc, B,which is rendered free to move forwardly and bachwardly by means ofguides which are combined with its frame and with the case of thecamera. Springs B', connected to the case of the camera and pressingagainst the frame ofthe focusing-plate B, serve to move said plateforwardly. This plate is located in the compartment fr ofthe case,whichis rearward ofthe main chamber or compart ment a'. The plate-holder maybe slipped into the compartment ai in front ot' the glass plate B andits frame. I have represented a plateholder, C, in place in thedrawings.

The rear of the compartment ci is closed by a slide, c5, which isprovided with tongues or Iianges at its edges. These tongues or liangesat their top and bottom edges tit in grooves in the walls of thecompartments a?, and the tongue Serial No. 252,559. (No model.)

or ilange which is at the inner end of the slide also enters a groove inthe contiguous wall ot' the compartment ai. By means of the tongues orllanges and grooves a lap joint will oe formed and light will beeffcctually excluded. At one corner the compartment a2 is provided witha cover, c, which is made L-shaped in cross section, connected at oneedge by hinges ai to the main portions of the case of the camera, andadapted to be secured at the other edge by means of any suitablelatch-as, for instance, a swinging latch, c, pivoted to the slide c, andadapted to engage with a screw or other projection upon said cover. Theedge ot' the cover a, which is adapted to close against the slide a", israbbeted,so as to litandoverlap the flange or tongue ofthe adjacent endofthe slide. A lap-joint is also preferably provided between the mainportion of the case and the cover where they come in contact.

The cover c may be swung open to expose the end of the plate-holder O atwhich the handles of its sliding covers are located, so as to admit ofthe withdrawal of the said sliding covers at pleasure. It also providesfor the insertion and removal of plate-holders. Vhcn closed, it concealsthe plate holders and tends to relieve the apparatus of the appearanceof a camera.

Forward ol' the main compartment or cham ber c is a compartment orchamber, ai. In it is located an adjustable lenstube. rthis adjustableleus-tube Iils within the tube D', which is fastened to the front of thepartition sepa rating the main compartment or chamber a from thecompartment or chamber a3. The adjustable lens-tube may betelescopically or longitudinally adjusted within the fixed tube. Theadjustable lens-tube has combined with it a lever, Di, which ispivotally connected at the upper end to a bracket, d, secured to theupper wall ofthe compartment ci, and which at the lower end projectsthrough a slot that extends lengthwise of the bottom of the compartmentc, rEhe middle portion of this lever is shown as formed into ayoke,which embraces the adjust-able lens tube and is connected to it. Asshown, the yoke portion of the lever is vertically slotted, and isconnected to the adjustable lens-tube by means of screws passing looselythrough its slots and entering tapped holes in said adjustablelens-tube.

The lower end of the lever D` is shown as extending into a compartment,which is located below the compartments u a2 as. At its extremity it isprovided with a handle, d', by which it may be conveniently manipulatedto shift the adj usiable lens-tube lengthwise of the camera for thepurpose or focusing. I have shown as combined with the lower end of thislever a pointer, d, which operates in conjunction with a sealebar, d3,which is graduated and marked so as to indicate the extent ofadjustments of the adjustable lens-tube which may be made.

The front ot' the compartment u is made in the form of a slide, a8, andis provided with tongues or flanges on its edges, which enter grooves inthe walls of the said compartment, forming joints which ettectuallyexcludelight. rlhis slide. as is provided with a hole opposite thelens-tube. This opening may be closed by a cap or disk, a. Vhen this capor disk is not needed, it may be placed in the compartment a3, and heldthere by a spring-iinger, uw.

I have shown a tinder arranged partly within the upper portion ot' thecompartment a and partly within the corresponding portion of thecompartmentaa. Opposite this finder there is a hole in the slide as. Theslide as is provided upon its rear with shutter mechanism, which may beof any suitable kind. I have shown a ily-shutter mechanism as arrangedupon it. The slide a8 may be retained in place by a button, a, or othersecuring device.

The compartment c" is deep enough to contain another plate holder, C. Itis provided with means for retaining such plateholder within it. Asshown, it is provided with a bar, al?, on one side of the wall and witha springcateh, al, at the opposite side. The handles ofthe slidingcovers of the plateholders may be made to engage with the bar al2 whenthe plate-holder is inserted, and then if the spring-catch be depressedthe plateholder may be swung into the compartment, and afterward thespriiig-eatch may be re- 'leased-and will engage with and retain theplate-holder in position within the compartment. The space of thecompartment a" is thus utilized in a very desirable manner.

The case of the camera may be provided with a handle, c, whereby thecamera may be conveniently carried.

Of course this camera may be used with a stand, if desirable.

XVhat I claim as my invention, and desire to secure by Letters Patentlisl. A photographic camera having a case divided by immovable partitionsinto four compartments, a main compartment or chamber at the middle, aforward compartment or chamber for accommodating an adjustablelens-tube, said adjustable lens-tube receiving support from a stationarytube mounted upon the immovable partition between said comor chamber foraccommodating a plate-holder and having its back made in the form ot' aslide, substantially as specified.

3. A photographic-plate holder having a4 case comprising a maincompartment or chamber and a rear compartment or chamber having its backmade in the Form of a slide, and having ahinged corner cover,substantially as speciiied.

4. A photographic camera having an adj nstable lens tube and a leverembracing said adjustable lens-tube and extending through the case ofthe camera, substantially as specified.

5. In a photographic camera, the combination of a fixed tube, atelescopically-or longitudinally adjustable lens-tube fitted thereto,and a leverl fulcrumed to the case of the camera at one end and at theother end extending through the same and connected to an adjustablelens-tube between its ends, substantially as specified.

6. In a photographic camera, the combination ofthe xed tube D, thelongitudinallyadjustable lens-tube D, and the lever D2, having a yokeembracing said adjustable lenstube, substantially as specified.

7. In a photographic camera, the combina` tion of the fixed tube D', thelongitudinallyadjustable lens tube D, the lever D", havinga yokeembracing said adjustable lens-tube, and the scale-bar d3, substantiallyas specified.

S. In a photographie camera having a case provided with a maincompartment or chamber and a chamber or compartment arranged beneath thesame, a device for detachably securing a plate-holderwithin said lastchamber, said device consisting of a bar adapted to engage the groovedside of said plateholder, and aspring contacting with said plate-holder,substantially as specified.
